eclipse - eclipse(开普勒):maven插件(m2e，1.4.0):

Question

我刚刚下载并安装了“Eclipse Eclipse for Java EE Developers”，这是一个软件包解决方案，其中包括m2e插件以及其他插件。

尝试在Eclipse中重建Maven中央存储库的索引时，出现以下错误:

"Unable to update index for central|http: //repo.maven.apache.org/maven2: [...]/.m2/repository/.cache/[...]/nexus-maven-repository-index.zip (Datei oder Verzeichnis nicht gefunden)"

检查该缓存，我发现文件“nexus-maven-repository-index.gz”，但没有zip文件。

我是否错过了Maven插件的某些配置选项？
如果没有，那是怎么回事？
(在central.maven.org/maven2/.index/处只有一个gz文件。那么为什么m2e搜索zip文件？)

非常感谢您的帮助。

为了将潜在的Eclipse问题与Maven问题分开，您可以尝试安装最新版本的Maven并将其设置为Eclipse(Windows>首选项> Maven)。
